Toallwhomz'tanay concern; 17 having a flexible ipe 18 lea to tho Bert that I, Cnanmis W. BENNETT, sigpply ofcom resse air. From t e tee a of Plttsburg, Alle heny county, Pennsylvav ved pipe 19 eads down into a closed tank nia, have invente 'anewanduseful Appara- 20, containing oil, which may be forced tus for Loosening Sheets, of which t e folthrough passage 21 into the cylinder to operlowmgis a full,;c ear, and exact description,

reference being. had to the accompanying downwardly, the compressed air act' v ,to force out the oil, or allow it to flowback l'he jib may be counterweighted as shown at 22. In Fig. 2, 23indicates the finishing rolls,- and 24 the stands with packs thereon, alongside Figure l'is a side elevation ofgny improved er sets of anannealed pack; and Fig. 2 IS ,a small plan view, showing the relatiin of the ac y invention relates to the ohsening of metal sheets, and particularly to the loosen- -mer extends.

In using the apparatus, the'cran'e is moved along the-track to the desired point, where it is stopped, and may then be he (:1 by books 25 if desired which engage the track rail. The

It has been found that'when metal sheets are annealed, the upper sheets of the} pile ome .overheated when the t is suflian' introduced to the hammer, and the upper sheets are thereby given a rapid series of blows which loosen them from each other. The hammer may be moved around to differ-,-

the centerand ower art of the ack. This ent parts of the pack by reason of the: ball overheat' causes t e 1 per s eets to .adbelie. 1 see other, and w en removed from the furnace it has been necessary to loosen them. This has been ordinarily done by tained by the weight which affords a yielding controlled by the cock or-valve 2.6-. The weight 13 serves to largely prevent the reve ll'y slow and laboriouswork. 3 he object of my invention is to rovide a oosenmg these anenables amore effective action to be imparted to the hammer. The springs 12 also assist intaking up the receil.

1Many changes ma and arrangement of the hammer, the method of mounting the same, the means for supplyingair, 'mventlon. 'I claim': s V l. Inpack-loosening apparatus, a horizontally extending support, a carrier .movabl'e on said su port, a pneumatic hammer attached to said carrier to move vertically with respect thereto, v thehaminer for holding the'same to its work and for preventing recoil andrebound therethe sheets of a pack, particularly In the drawings, in which I show a pie rails of a track, on WhlC travels a wheel carunger 4 and a movable cylinder 5 carrying. the jib 6.- The jib is formed-with a suitable inner track on which travel the wheels of a small trolley 7, in which isloosely mounted a lar e ball 8, fo'rmhrcugh'a vertical hole in this. ball extends the barrel 9 of a neumatic hammer, having a stationary colby the vertical and to also {take the recoil substantially as described.

.'2.- In pack -loosenin'g.apparatus, a hori- *zontall'y 9 is capableof a vertical movement of: the hammer,- a. e amount rests .upon t e movable washer A tool or head 14 of the lpneun'natie ham e 'ty e, andthe b handles 15. have shown the air as supplie fromaflexi; ble hose 16 extending from a tee orfixture above the. support, said hammer havin a jib is then brought to the desired heat," the joint, while the resistance for the blow is obresistance. ;The air t9 the hammer may be movements of the hammer-- of-which the track for thepneumatic hambound of the hammer when inaction and also be made in the form I &c., without departing from my.

a weight mounted on .100. of, and sprmgsarran'ged to be compressed extending support, a carrier mov-' able onthe support, a pneumatic hammer 'from' the carrier andextending" ball-and-socketiconnection with the carrier,

a weight mounted on the upper portion of the hammer, and a spring so porting said weight the hammer belng capa le of vertical movement through the ball and socket connection, substantially as described.

3. In apparatus of the character described, a supp rt, a carrier movable horizontally on salt support, a pneumatic hammer attached to said carrier, and capable of vertical movement with respect thereto, said hammer having its barrel or casing Weighted, and spring means acting upon the barrel or cas ng to cushion its movements; substantially as described.

4. in apparatus of the character described, a support, a carrier movable horizontally on said support, a pneumatic hammer having a ball and socket connection with the carrier, the barrel orcasing of the hammer being vertically movable through the ball and socket connection, and spring means acting upon the barrel or casing to cushion the movements thereof; substantially as described.

In testimony whereof, I have hereunto set my hand.
